HDS03.1-W075N-HT14-01-FW
The HDS03.1-W075N-HT14-01-FW is a multi-axis drive module produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as the power and control stage between the supply unit and synchronous or induction motors, regulating torque and velocity in industrial automation lines. By interpreting standardized command telegrams from upstream motion processors, it supports closed-loop axis control without separate analog reference signals. The model is intended for coordinated motion tasks in transfer systems, packaging equipment, and other automated lines that use centralized motion control. Its modular format fits machine layouts where several controllers operate from the same supply section.
The controller exchanges real-time setpoints and feedback across the optical SERCOS interface, which supports synchronized communication between the control system and the drive. It belongs to the DIAX04 family and uses a built-in air blower for heat sink cooling. This cooling method pulls air through the heat sink without requiring a separate external fan assembly. The unit is part of Line 03 and supports a continuous output current of 75 A, making it suitable for medium-power servo axes. That current level allows steady motor control during continuous industrial duty. The drive is Version 1 and is classified as an HDS drive controller for position and velocity loops under digital feedback.
In multi-axis systems, the module operates beside other controllers on a common DC bus, allowing energy exchange during acceleration and braking. Returned energy from decelerating axes can be shared on the bus instead of being handled as isolated power events at each axis. This arrangement reduces separate power distribution hardware and supports regenerative operation within a shared supply section. The design is well suited to modular machine assemblies where several axes must be coordinated through one control architecture.
